{"abstract":"We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD was prompted by changes to the airworthiness limitations, which add life-limited landing gear parts not previously identified. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new airworthiness limitations that add life limits for previously unidentified landing gear parts. We are issuing this AD to address the unsafe condition on these products.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2017/05/25/2017-10284.html","cfr_references":[{"chapter":null,"citation_url":null,"part":39,"title":14}],"citation":"82 FR 24013","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This AD is effective June 29, 2017.","disposition_notes":null,"docket_ids":["Docket No. FAA-2016-9507","Directorate Identifier 2016-NM-127-AD","Amendment 39-18878","AD 2017-10-04"],"dockets":[{"supporting_documents":[{"title":"TR  28-1 EMB","document_id":"FAA-2016-9507-0008"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2016-9507-0007"},{"title":"Response to EMBRAER Comment","document_id":"FAA-2016-9507-0006"},{"title":"U.S. DOT/FAA - Supporting AD Documents","document_id":"FAA-2016-9507-0005"},{"title":"U.S. DOT/FAA - Supplemental AD Documents","document_id":"FAA-2016-9507-0003"}],"agency_name":"FAA","documents":[{"comment_count":0,"comment_start_date":"2017-05-25","updated_at":"2023-03-01T15:59:08.811-05:00","comment_url":"https://www.regulations.gov/commenton/FAA-2016-9507-0004","allow_late_comments":null,"id":"FAA-2016-9507-0004","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":5,"id":"FAA-2016-9507","title":"Airworthiness Directives: Empresa Brasileira de Aeronautica S.A.
